PVA hydrogels, PVA crosslinked with GA (PVA/GA) and PVA derived hybrids (PVA/GA/TEOS, PVA/TEOS) were milled and mixed in a ratio of 1.0% (wt. (%)) to KBr powder dried for 24 hours at 120 °C. FTIR ...

This is consistent with the FTIR results, which detected both layers 2 and 4 being related to polyamide, but with layer 2 comprising of another co-polymer, such as PVA. FTIR-micro will not be able to ...

(d) Figure 1. FTIR analysis of HAP/PVA/GEL Film (S1, S2) and of HAP/PVA/GEL/Glycerin Film (S3, S4). The first small peak was at 3670 cm − 1 in S1 and S3 and 3668 cm − 1 in S2 and S4 which indicated ...

2.1 Physical properties. The Fourier-Transform Infrared Spectroscopy (FTIR) analysis of the samples was performed. The equipment used was Perkin Elmer Spectrum GX (DCU), 16 scans per samples in the ...

As shown in Figure 2, the FTIR spectrum of pure PVA exhibits several bands characteristic of stretching and bending vibrations of O - H, C - H, C = C and C - O groups.A broad and very strong band ...

Synthesis and Characterization of PVA Mixed Matrix Membrane Containing NaP Zeolite/Charcoal-Based Graphene Oxide Nanohybrid for Dehydration of Isopropanol by Pervaporation Mohammad Hosein Moghadasin ...

FTIR spectra indicated characteristic absorption peaks related to the chemical structure of PVA, fibroin and Ag NPs, it demonstrated good interactions between them, caused by strong intermolecular ...

FT-IR analysis of the ChS-PVA blend membrane showed the strong interactions between the amines of ChS and hydroxyl groups of PVA through chemical cross-linking by hydrogen bonding. More importantly, ...

To be able to compare those values, a correction of the FTIR absorption intensity of PVA-MMT coatings could also be conducted to deduct the effect of clay if needed. 5. Conclusions. Crosslinking ...

Silicon Carbide (SiC) with and without adding Polyvinyl-Alcohol (PVA) were prepared and investigated both as an electrolyte solution and body motion sensor. The characteristics of SiC-based ...
